[0022] like Figure 1-3 As shown, the utility model provides a technical solution: a precise metering device for powdered medicine, comprising: a dustproof box 1, a high-precision electronic scale 6, a container 7 and a discharge piece;

[0023] The container 7 is installed in the placement area of ​​the high-precision electronic scale 6. The container 7 is provided with a material receiving port 703 and a through hole 704. The discharge piece is connected to the inside of the container 7 through the through hole 704 to discharge the material in the container 7. The discharge piece is a device that can generate airflow. By generating airflow, negative pressure is generated at one end connected to the container 7. The material is sucked away by the negative pressure to realize automatic material removal after weighing.

[0024] like Figure 1 and Figure 2 As shown, for the smooth implementation of this embodiment, it is necessary to know that a conical material box 2 is installed on the top of the dustproof box 1, and a conduit 3 arranged inside the dustproof box 1 is fixed at the bottom end of the material box 2, and the conduit 3 is directly above the receiving port 703 of the containing box 7. The device pre-prepares powder material through the material box 2, and loads the powder material from the material box 2 into the containing box 7 for weighing. A horizontal plate is fixed on the top of the material box 2, and a micro-auger 4 arranged in the conduit 3 is rotatable at the bottom of the horizontal plate. A motor 5 for driving the micro-auger 4 is installed on the horizontal plate, and the micro-auger 4 is driven by the motor 5 to rotate to transport the powder. The motor 5 is a stepping motor, which can effectively control the auger speed, realize precise control of the auger, and facilitate precise control of the material. Starting the motor 5 can accurately deliver the material into the containing box 7.

[0025] like Figure 1 and Figure 2As shown, for the smooth implementation of this embodiment, it is necessary to know that the container 7 includes a material cup 701, a cover sheet 702 is fixed on the top of the material cup 701, a notch is provided between the cover sheet 702 and the edge of the material cup 701 to form a material receiving port 703, a through hole 704 is provided at the cover sheet 702, and the discharge part includes a discharge pipe 8, the discharge pipe 8 is connected to the dustproof box 1, one end of the discharge pipe 8 in the dustproof box 1 passes through the through hole 704 and is connected to the material cup 701, a gap is provided between the surface of the discharge pipe 8 and the through hole 704, and the discharge part also includes a branch pipe connected to the discharge pipe 8 A guide 9 for providing airflow into the discharge pipe 8 is fixed at the end of the branch pipe. In the design of the discharge member, the guide 9 is connected to the discharge pipe 8 to guide the flow of air. When the flow velocity in the discharge pipe 8 is fast and the airflow direction is away from the dustproof box 1, a negative pressure is formed at the end of the discharge pipe 8, so that the medicine can be evenly discharged. The guide 9 is a device that can provide high-speed airflow, and can be composed of a shell with electrically driven blades installed inside, which generates airflow through high-speed rotating blades, or it can be an airflow pump, which generates airflow through the pump to form negative pressure to discharge the powder.

[0026] like Figure 3 As shown, for the smooth implementation of this embodiment, it is necessary to know that a gap is provided between one end of the discharge pipe 8 connected to the container 7 and the inner wall surface of the material cup 701, and the gap is 0.2mm-0.5mm. This gap is designed to prevent the medicine from being obstructed during the transportation process, and at the same time reduce the distance between the end of the discharge pipe 8 and the medicine powder, so that the medicine powder can be efficiently sucked away, and at the same time, it can also ensure the smooth flow of airflow. At the same time, the inner wall of the material cup 701 is curved and the inner wall surface is smooth, so that the powder medicine enters the material cup 701 and automatically gathers in the middle under gravity, which is convenient for the discharge pipe 8 to guide the powder out.
